Snowball Problem: Differential Equation of Translational Motion

  • Thread starter sheelbe999
  • Start date
In summary, the snowball's translational motion can be described by the differential equation F=mg sin(*)=m dv/dt + a v^2, where the additional mass accumulated is proportional to the distance traveled and friction and rotation are ignored. The equation takes into account the forces acting on the snowball and its acceleration as it slides down the inclined slope.

Homework Statement


"A snowball, initially of mass m, slides down a slope inclined at an angle φ with
respect to the horizontal. As it moves, the mass of additional snow Δm = αx that it
accumulates is proportional to the distance traveled x. Write the differential equation
of translational motion for the snowball, ignoring rotation and friction. [6]"

I was sure mass was irrelevant in this situation? But judging by the question its not. Could anyone help me out?

As always, I'd begin by drawing a picture; what Force(s) act on the snowball, and which direction do they point?
 
  • #3
F=d(mv)/dt
F=v dm/dt + m dv/dt

m=m+ax
dm/dt=av

F=mg sin(*)

mg sin(*)=m dv/dt + a v^2
